Modern Military Fiction Recommendations

Howdy!

I am looking for book suggestions for Fiction Modern Warfare / Future Warfare. World War 3 type stuff, or even Science Fiction.

I love Military Action and Tactics, Strategy type books. I also really enjoy espionage thrillers.
But to make this a bit easier on what I've read plus an idea of what I'm trying to find, here is the list:

1) Red Storm Rising – Dear God I loved this book. It's why I'm here.

2) Starship Troopers – Probably one of my favorite books of all time.

3) Future War – Yup.

4) Armor

5) Hunt for Red October

Let's just say no Tom Clancy, I'm already going through that list. Needing new authors.

Also, I've really enjoyed non-fiction War Books: Outlaw Platoon and Red Platoon are two of the best books I've ever read.

I really appreciate suggestions, I'll even take wild cards cause you never know when there's a hidden gem someone else could lead you to! Thank you very much in advance!
